The opening of Daphne Guinness’ clothing collection at FIT was the perfect way to close out Fashion Week. Guests Thursday night included designers Valentino, Calvin Klein, Oscar de la Renta and Zac Posen, Bergdorf Goodman’s Linda Fargo and MAC’s John Demsey. While the show features the works of Karl Lagerfeld, Gareth Pugh and the late Alexander McQueen, Daphne decided to wear a piece by a young designer Hogan McLaughlin, whom she discovered on Twitter. The sparkling silver jacket she wore required two security guards to stop people from stepping on the train. Despite all the hoopla, Daphne was sweet and greeted everyone who came up to her. Andre Balazs was seen frantically texting by the exit as the party wound down before making a mad dash out the door. Susanne Bartsch, who split with beefy gym founder David Barton last year, came with a long-haired young man in a black skirt whose posterior she kept grabbing while posing for pictures.
